Suppose it depends on how the shimmer is created. First, Frontosa generally are lower light fish, so you would not want searing lights over the tank.
But if you created this shimmer with filter outlets running across the top of the tank and had a single point of light they should be ok. I'd steer away from lights like Metal Halides and other super bright lights however.
Easy enough to test - set it up, but give the Fronts plenty of hiding spots. If they stay hidden and don't behave normally, odds are they don't like the set up.
